Feed reads could fail with a generic internal server error even when the remote endpoint was actively rejecting the request, which made debugging 403/500 responses difficult and forced callers to do pre-flight checks.

• Summary

  • HTTP errors returned by remote feeds were being collapsed into a single generic message.
  • This obscured the real server status and made valid-feed failures look like internal library faults.

• What changed

  • The HTTP adapter now builds the exception message from the actual PSR-7 response status code and reason phrase.
  • ServerErrorException now reports values like Server responded with: 403 Forbidden instead of the hard-coded internal server error.
  • The regression is covered with explicit 403 and generic server-error assertions to keep the contract stable.

• Example

try {
    $feedIo->read('https://www.jeuxvideo-live.com/feed');
} catch (\Throwable $e) {
    echo $e->getMessage();
    // Server responded with: 403 Forbidden
}
